10. Administrative building AIL – Aziende Industriali di Lugano (Muzzano – Switzerland), Leader: SUPSI
The administrative building of AIL (Aziende Industriali di Lugano) is located in Muzzano, Switzerland. The building was built in 60’s ages, and it is actually heated through a gas co-generator, thermal solar panels and a gas burner. In
2017 the construction site began, with the goal of a complete energetic refurbishment of the building and the creation of new offices.
The Energetic Reference Area of the completed building is about 6’000 m2(3’500m2 for the refurbishment and 2’500m2 for the new building part). The gas co-generator and the gas burner are going to be decommissioned, and the future heat will be produced through heat pumps coupled with boreholes heat exchangers. Solar panels will be kept on the roof.
The building will also be cooled (only sensitive cooling) in order to regenerate the ground. The GSHE will comprise more than 4 boreholes and in accordance with Suisse normative (SIA 384/6) a dynamic simulation of the operating GHSP system was performed. The end of the retrofit is expected during 2018, and thanks to several smart meters, it will be possible to compare the heat consumption before and after the refurbishment. The project is following the Suisse energy label for sustainable buildings called Minergie. A ground response test was performed, in order to know the thermal ground parameters and the length of the GSHE required. All the costs of the refurbishment will be available.
